Brassicaceae, Chenopodiaceae ve Urticaceae Familyalarına Ait Bazı Bitki Türlerinin Arbusküler Mikorhizal Fungus (AMF) ve Rhizobacteria Arasındaki İlişki

This study was conducted to investigate the effects of some plant growth-promoting rhizobacteria (PGPR) on arbuscular mycorrhizal fungi (AMF) formation [Brassica oleracea (cauliflower), Spinacia (spinach) ,and Urtica urens (stinging nettle)] belonging Brassicaceae, Chenopodiaceae and Urticaceae families, which are known have a negative influence symbiotic life with AMF. Two PGPR isolates that contributed plant's growth served as “mycorrhizal helper” in various hosts were predetermined at initial stage; then they applied three species AMF [Gigaspora margarita commercial (ERS)]. The obtained results revealed combined x treatments improved morphological development parameters cauliflower, spinach, nettle plants. bacteria had different root colonization depending species. highest rate achieved spinach plants treatments. Commercial isolate, alone or combination strains, also found increase spore density dependency cauliflower There no significant difference total phosphorus content compared control group, only one application group (G. PGPR) an content.
